Book Description
This publication is rare among those texts on pesticides in that it covers herbicides exclusively. It presents, in one source, information that is typically scattered. This important publication enables the reader to recommend herbicide use more reliably and efficiently. It also highlights environmental issues relevant to herbicide use in agriculture. The book outlines potential areas of further research. This title is of particular value to weed scientists, environmental chemists and engineers, soil scientists, and those responsible for recommending and/or regulating use of herbicides in agriculture. Focuses On: ? Increasing efficiency of herbicides in agriculture ? Decreasing environmental contamination with herbicides ? Dissipation and transformations in water and sediment ? Nature, transport, and fate of airborne residues ? Absorption and transport in plants ? Transformations in biosphere ? Bioaccumulation and food chain accumulation ? Photochemical transformations ? Bound residues ? Predictability and environmental chemistry

Book Description
Conveniently gathering up-to-date information on herbicides' chemistry, degradation, and mode of action in one source, this reference discusses glyphosate and the traits that have made it so successful ... investigates the adsorption of polycyclic alkanoic acids' ester into targeted plants ... documents sulfonylureas' selectivity, environmental compatibility, groundwater safety, and low use rate ... explains metribuzin's combination with other herbicides to increase weed control for soybeans, potatoes, and tomatoes ... and examines alachlor and metolachlor for controlling annual grasses, broadleaf weeds, yellow nutsedge in corn, soybeans, and many other crops. Extensively referenced and illustrated, Herbicides, Volume 3 is an outstanding reference for soil scientists, agronomists, microbiologists, biochemists, agricultural chemists, botanists, environmental scientists, and plant nutritionists and pathologists.

Book Description
Field and laboratory studies of the movement of herbicides were conducted to determine their potential as contaminants in irrigation return flow. Special emphasis was given to the use of herbicides for vegetation control along ditches, canals and watersheds where high dosages are required to control the excessive growth of grasses and broadleaved weeds. The following herbicides have been studies: substituted urea (diuron), triazines (summitol and atrazine), phenoxyacetic acid (2, 4-D and 2, 4, 5-T) and a substituted pyridine (picloram). The greatest tendency for transport of herbicides in water coming in contact with soils occurs during the initial storms following spray application. If the intensity of the initial precipitation is not sufficient to cause movement across the soil, the danger of herbicide movement is essentially eliminated. The highest concentratoins (ppm) of herbicide observed in surface waters were 1.8, 0.5, 4.2 and 2.7 for diuron, summitol, 2, 4-D, 2, 4, 5-T and picloram, respectively. These levels were observed immediately below treated areas receiving the higher recommended dosages of the herbicides. All herbicide concentrations dropped below the limit of detection within a few hundred meters below the sprayed areas. Presumably, soil filtration, adsorption and dilution are primarily responsible for the loss of herbicides from water.
